structions, and lcombinations of parts, hereinafterdescribed and claimed.

The object of the'invention is to provide ay simply constructed, and easily operated explosion engine of the rotary type, Wherein a governor mechanism is provided for vcontrolling the fuel supply, in addition to .the usual cam operated inlet valve.

l'Referring to the drawings 'forming a part hereof Figure l is a side view of the improvement partlyfyinv section, Fig. 2 is a plan view, Fig. 31 is a transverse vertical section, Fig. 4 is an end View of the piston, Fig,5 is aside view ofthe iy Wheel, Fig. 6` is a section on the line 6 6 of Fig. 5, Fig.

isa .section on the line or the Wedge, and

."Figtf is aside and front View respectively [of the cams.

The embodiment or"l the iaivention shown in -the drawings comprises a base 1, which vmay be ofi any suitable or desu-ed construcr tion,i,an'd the cylinder consisting of a shell and heads 3 and 4 is supported on the base. 4,The .shell is'provided at its ends with lateral flanges 5, which lap on the base, andare secured thereto by bolts 6.

v f. Therotor'comprisesa shaft 7, which is journaled in bearings S on the base, and a cylinder.

15, which extend to the free edges of the afanes.

Packing rings 1G are arranged in'cach of I the grooves, and are supported by springs l?, seated between the rings and the bottoms of the grooves, and each ring is pro-- 22, secured in place by cap screws 23. It A Will be noticed that the peripherynof the rotor is eccentric to the sha-ft so that when the rotor moves in the direction of the arrow shown in Fig. 3, theabutment will be lifted to permit the vane to pass thereby.

The sparking device 25 is arranged in the lexplosion chamber, at its outlet-,into the cylinder. The sparking device comprises a ixed electrode 26, and a movable electrode 27, arranged on the end of a shaft 28. The shaft is j ournaled in bearing 29 on the cylinder, and outer end thereof is provided with a crank arm 30.

A cam 31 is secured to the shaft adjacent to the cylinder, and a lever 82 is pivoted by one end to the cylinder as at 33, the opposite end engaging the cam. A link 34 connects the crank arm 30 with the lever 32, and a spring 85 vpresses the lever against the cam.

It will be evident that when the shaft 7 rotates, the movable electrode will engage the fixed electrode at regular intervals, and the usual jump coil and batteries or other source of electrical energy is arranged in circuit with the electrodes thereby to produc-e a spark when the electrode,` disengage. Such construct-ion however forms no part of the invention, and it is not thought necessary to illustrate the same.

The explosive mixture is conducted to the explosion chamber by a pipe 36, Which delivers at the outer end of the chamber, and

by a valve 37, which is usually held closed,

and is opened at regular intervals by an arm 3l), on a sha-it l0, journaled in bearings lll ou the cylinder.

The outer enc. or the shait itl is provided. with the arm f-"Q, which is ennected by a linli 43, with a lever f ll f :ted as et d5 on the adjacent fgsylinder li cf the lever is nor; "ll-v nient with a cani .means o'li sjliril 4.

taies 1the cam. all) will ce lo open the valve regrilar intervals, to admit a supply ci niiftnic. The cams 3l and -fl are :irren i operate .in sequence, so that the che. e is i nited at the proper time.' '.lhe supply oi explosive mixture is further regulated by ali/e d), arranged in a casing' interposed in the supply pipe. The valve is ci tl'ie rotary ty; e, and is provided with a stein 5l ent-ending outside eilt the valve casing, and. providi-d with a crank. arm 53.

A lever 53 p' f ze' by its center a bracket 511.- on the bv 1, and cue end of the lever is connected by a linlt iii with the crank, arm 52. The other end is provided with n fork 53, having set s 'ens lill tlirezldcd therethrough,and the set screws engage opere ings in blocks 53, which nieve in an. annuler vgroove 56 in a cellar slideble longitiuflr nelly" el the shaft 'i'.

f he cellar is fi'n'ef/idedon Witl. radial gnoorwY ce, Whici radial groeves in. tie heb (l0, oit a ily Wheel el secured te 'the sind?, 7. llevers t are piyeted on spokes {l o. the ily ndice/l, the Onterend er1' each ol? said levers having' a Weight 641,'

The levers are two in number, and are arranged at diametrically opposite points, and the weighted ends are adapted to be thrown outward when the fly Wheel rotates, hy centrifugal force. When the weighted ends move outward, the 'Wedges are moved radially inward, and the collar 57 is pressed away from Ythe fiy Wheel, against the resistance et the .springs 70, which normally press it toward the said fly Wheel. `When the cellar moves away from the fly wheel, the lever it? is rocked, and through the link 55 the vi is rotated.

The arrangement of the i .ve is such that whenv the engine is rui M icri'nal speed, the valve will be sbl opened.` When the speed the engine exceeds this speed, the governer mechanism just de' scribed eperates to 'p rlially close the valve, and When it Y i l ill th., speed the valve is f greater siu'wll In epe ,i. ....5 i. suitable l,

determined l, to admit a 4er with i ,enigme charges oli explosive mixture will be drawn into the explosion. chamber, i ited and. passed into the cylinder. The lice of the explosion will be exerted on the wing or vane, and on the abutment 22, and since the abutment lined, the piston will rotate. .lust-lieim'e the other vane passes the inlet, the iii-st vane pass s the exhaust port 68,V and the products ot combustion pass out of the cylinder. The second vane then asses the inlet and receives the force of t e ex- ].ilosion of the next charge. The cams 31 and L6 are arranged to cperate their reective mechanisms twice during each roicn of the. shaft 7. 4 Springs 6E) are arranged between the oute ends ci' the levers 62 and the spokes, and normally draw the Weighted ends of the levers inwardly, and the wedges outwardly, and other sp1-ings 70, arranged between the cellar 57 and the fly wheel assist in this action.

The casing of the cylinder is water-jacueed, L shown at 7], and is supplied w1th a cooling fluid by pipes 72, and the piston is heilmv as shown at 73 for receiving a cooling fluidl The cooling mixture may be supplied to the piston in any suitable manner. Such inecnanisni forming, however, no part el i ie invention, has not been shown nor der ed. The extensions 18 of the pecking ringe are also shown as sectional, Fig. 4.
